I DEVICE FOR CATCHING AND STACKING SHEET MATERIAL Filed Sept. 29, 1930 2. Sheets-Sheet 2 o o m sheets being delivered. As fast as the sheets are stacked upon the table 14 they are removed by one or two attendants; The table of these side stops 30is adjustably supported in a keeper 31by meansV of a rack bar"32 which may be l adjusted inwardlyior outwardly ofthe keeper by means of a pinion 33 in engagement with the rack'bar and se cured to a shaft 34 which extends outwardly 0f the keeper and is provided with'a knob 35 `or other :means for rotating it. The keeper 31 'mayy be adjusted longitudinally ofy the table and secured to one'of the slats 15 by means of a cleat 36 secured to the bottom of the keeper anda cam 37 which cooperates with the `cleat 36 to clamp the keeper to the slat at-any point along the length of the table. The cam 37 is secured to a spindle `38 which extends through the wall of the keeper and is provided with a handle 39 for rotating the same. r f

f. lFrom the foregoing description it will be seen that I have provided means for stacking the sheets automatically as they are delivered from the conveyoror processmachineryand that thestacking device may be adjusted'for sheets of any length or Width. The sheets ma thus be handled most advantageously an the edges ofthe same will not be injured. TheV device is particularly adapted for. use .with modern high speed machinery.

i' While I have shown and described specifically the preferred form of the invention, it is apparent that thesame may be considerably modified without departing materially from the scope of the invention as claimed. @What I claim is: f

1. 'A table for receiving and stacking sheets `and-provided with spaced stops for engaging rthe ends of the sheets, a pair ofside stops, .and means for selectively securing said side `stops to the table inopposed relation to each .other and at different distancesapart to accord with the width of the'sheets delivered 'from the conveyor. U

`1 2.' A table for receiving and stacking sheets of material and comprising longitudinally disposed spaced slats, spaced stops for engaging the ends'of the sheets, a pair of side stops, means for selectively securing said side stops to said slats and in opposed relaftion to each other, and meansv for adjusting Ysaid-side'v stops Vso that the distance between them will accord with the width ofthe sheets to be stacked.

theends of the sheets, a pair of side stops,

keepers in which the side stops are mounted, means for selectively securing the keepers to the slats at various distances from the longitudinal center line of the table, and means vfor adjusting the side stops with reference toythe` keepers toward or away fromy saidA center line.

4. A table for receiving and stacking sheets i and provided with two opposed stops adaptedto engage opposite ends of the Vsheets de livered thereto, one stop being fixed, the

other stop being carried by the table' and Y disposedin'the path ofthe sheets as the larel delivered, andA means including a rac and pinioirfoi" adjusting the table together withthe. last mentioned stop longitudinally to accord with the length of the sheets to be stacked.

A table Vadjusting the table togethery with the last mentioned stop longitudinally to accord with thelength of the sheets to be stacked.

56. In combination,` a table for: catching and receiving sheets of material, ahorizontal endless conveyor above the plane of the table and in position to deliver the sheets over one end thereof, said table being provided with two opposed stopsadapted to engage opposite ends of the sheet, thestop at the end over which the sheetis delivered to the table being fixed, -a spring yieldably` urgingA the other Y stop toward the delivery means in the ypath of the sheet as the latter is delivered'to'the table, an abutment limitingthe movement of Vand stacking sheets o f material, ahorizontal endless conveyor above the plane ofthe table and in position vto deliver ysheets over one end thereof, said table being provided with tw'ovopposed stops adapted to engage opposite ends of the sheetsv delivered thereto,
